[0014] Furthermore, the cross-sectional dimensions of the collection hopper gradually decrease from top to bottom, and its cross-sectional shape is rectangular or square.
[0015] Furthermore, the filter device is connected to the sealing cap.
[0016] Furthermore, the collection hopper is equipped with a viewing mirror.
[0017] The beneficial effects of this application are:
[0018] The landfill leachate collection assembly provided in this application embodiment is used to collect leachate from an incinerator and filter the leachate using a filtration device. When large particles of impurities deposit on the filtration device and clog it, the sealing cover can be removed and the filtration device taken out of the inspection hole for cleaning. Once the sealing cover is removed, the leachate in the collection hopper will flow into the collection tank through the inspection hole, and then the leachate will be discharged from the collection tank through the drain pipe and finally flow into the main collection pipe, effectively preventing the leachate from overflowing from the inspection hole onto the platform outside the equipment and polluting the site environment.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0045] In the waste incineration power generation process, the leachate in the incinerator is collected by the waste leachate collecting assembly and then discharged into the leachate collecting tank through the leachate collecting pipe for centralized treatment.
[0046] Referring to Figure 1 , the existing waste leachate collecting assembly 1 includes a collecting bucket 10 and a collecting main pipe 11 communicated with the lower end of the collecting bucket 10 and extending downward, the lower end of the inner cavity of the collecting bucket 10 is provided with a filtering device 12, the lower end of the sidewall of the collecting bucket 10 is provided with an inspection hole 13, and the inspection hole 13 is provided with a sealing cover 14. Among them, the collecting bucket 10 is used to be arranged below the leachate outlet of the incinerator, and the lower end of the collecting main pipe 11 is used to be communicated with the leachate collecting tank through the leachate collecting pipe. When working, the leachate in the incinerator enters the collecting bucket 10, is filtered by the filtering device 12, enters the collecting main pipe 11, and is then discharged into the leachate collecting tank through the leachate collecting pipe for centralized treatment.
[0047] During the leachate collecting process, the large-particle impurities deposited on the filtering device 12 will block the filtering device 12, so the filtering device 12 needs to be removed regularly for cleaning. The specific operation process is: first, remove the sealing cover 14, and then take out the filtering device 12 from the inspection hole 13 for cleaning. However, once the sealing cover is removed, the leachate in the collecting bucket 10 will overflow from the inspection hole 13 to the platform 15 outside the collecting bucket 10, causing environmental pollution.
[0048] Based on this, referring to Figure 2 , the present application provides a waste leachate collecting assembly 2, which includes a collecting bucket 20 and a collecting main pipe 21 communicated with the lower end of the collecting bucket 20 and extending downward, the lower end of the inner cavity of the collecting bucket 20 is provided with a filtering device 22, the lower end of the sidewall of the collecting bucket 20 is provided with an inspection hole 23, and the inspection hole 23 is provided with a sealing cover 24; a collecting box 25 with an open top is arranged below the inspection hole 23, the collecting box 25 is used to collect the leachate overflowing from the inspection hole 23, the bottom of the collecting box 25 is communicated with a downward extending drain pipe 26, and the lower end of the drain pipe 26 is communicated with the collecting main pipe 21.
[0049] Referring to Figure 2The garbage leachate collecting assembly 2 provided by the embodiment of the present application is used for collecting the leachate in the incinerator. The collecting bucket 20 is arranged below the leachate outlet at the bottom of the incinerator, and the lower end of the collecting main pipe 21 is communicated with the leachate collecting pool through the leachate collecting pipe. The specific collecting process is as follows: the leachate in the incinerator first flows into the collecting bucket 20, is filtered by the filtering device 22, and then flows into the collecting main pipe 21, and is discharged into the leachate collecting pool through the leachate collecting pipe for centralized treatment.
[0050] Referring to Figure 2 With the progress of the leachate collecting work, the large-particle impurities in the leachate will gradually deposit on the filtering device 22. With the increase of the impurities on the filtering device 22, when the impurities increase to a certain amount, the filtering device 22 will be blocked, the leachate will be accumulated above the filtering device 22, and the discharge of the leachate will be affected. At this time, the filtering device 22 needs to be disassembled and cleaned. The specific cleaning process is as follows: first, the sealing cover 24 is removed. At this time, the leachate in the collecting bucket 20 flows into the collecting box 25 through the manhole, and is discharged into the collecting main pipe 21 through the drain pipe 26. Then, the filtering device 22 is taken out from the manhole 23, and is washed by using a high-pressure water gun to remove the deposited impurities on the filtering device 22. Then, the cleaned filtering device 22 is passed through the manhole 23 and is installed in the inner cavity of the collecting bucket 20. Finally, the sealing cover 24 is sealed and installed on the manhole 23 to block the manhole 23.
[0051] The garbage leachate collecting assembly 2 provided by the embodiment of the present application can be installed on site in two sets to be used in cooperation. Correspondingly, when the first set of garbage leachate collecting assembly 2 is used to collect the leachate, the filtering device 22 in the second set of garbage leachate collecting assembly 2 can be disassembled and cleaned. When the second set of garbage leachate collecting assembly 2 is used to collect the leachate, the filtering device 22 in the first set of garbage leachate collecting assembly 2 can be disassembled and cleaned. In this way, the continuous collection of the leachate can be realized. Of course, more than two sets of garbage leachate collecting assemblies 2 can also be installed on site to be used in cooperation, which is not limited herein.
[0052] When the filtering device 22 needs to be cleaned, once the sealing cover 24 is removed, the leachate in the collecting bucket 20 will flow into the collecting box 25 through the manhole 23. The leachate is discharged from the collecting box 25 through the drain pipe 26, and finally flows into the collecting main pipe 21. The leachate is effectively prevented from overflowing from the manhole 23 to the platform 30 outside the equipment, and the pollution of the on-site environment is avoided.
[0053] In some embodiments, referring to Figure 2The collecting box 25 is provided with a filtering assembly for filtering the leachate. Accordingly, the filtering assembly can filter the leachate flowing into the collecting box 25, so that large-particle impurities in the leachate are deposited on the filtering assembly, reducing the amount of impurities entering the collecting main pipe 21.
[0054] For example, referring to Figure 2 The filtering assembly includes a horizontally arranged filtering screen 27, which is detachably connected with the collecting box 25. The detachable connection can facilitate the disassembly and assembly of the filtering screen 27, thereby facilitating the cleaning of the filtering screen 27. For example, the filtering screen 27 and the collecting box 25 can be connected by bolts or buckle structures,
[0055] For example, referring to Figure 2 The filtering assembly further includes a filter core 28 arranged below the filtering screen 27 and connected with the upper end of the drain pipe 26. Thus, the filtering screen 27 and the filter core 28 can form a two-stage filtering structure, thereby improving the filtering effect of the leachate and further reducing the amount of impurities entering the collecting main pipe 21. The filter core 28 is detachably connected with the drain pipe 26, which can facilitate the disassembly and assembly of the filter core 28, thereby facilitating the cleaning of the filter core 28.
[0056] The sealing cover 24 and the sidewall of the collecting bucket 20 can be connected by a quick-release structure. In some embodiments, referring to Figure 2 The sealing cover 24 and the sidewall of the collecting bucket 20 are bolted. Accordingly, the bolted connection can be used in combination with a sealing gasket to enhance the sealing effect between the sealing cover 24 and the sidewall of the collecting bucket 20, prevent the leachate from leaking, and facilitate the disassembly and assembly of the sealing cover 24, thereby facilitating regular maintenance and cleaning work and improving the convenience of operation.
[0057] In some embodiments, referring to Figure 2 The cross-sectional size of the collecting bucket 20 gradually decreases from top to bottom, and the cross-sectional shape is rectangular or square. Accordingly, the gradually decreasing cross-sectional size helps guide the leachate to flow to the center of the collecting bucket 20, thereby facilitating collection and discharge. Since the cross-sectional shape is rectangular or square, the collecting bucket 20 can be spliced from four trapezoidal plates, thereby reducing the manufacturing cost.
[0058] The lower end of the inner surface of the collecting bucket 20 can be fixed with a support plate, and the filtering device 22 can be placed on the support plate and cover the upper end of the collecting main pipe 21. The filtering device 22 can be a monolithic structure or a spliced structure, as long as it can pass through the manhole 23.
[0059] In some embodiments, referring to Figure 2The filter device 22 is connected with the sealing cover 24. Accordingly, the structure not only supports the filter device 22 by the sealing cover 24, but also removes the filter device 22 simultaneously once the sealing cover 24 is removed, improving the work efficiency. In order to observe the flow condition of the percolate in the collecting hopper 20, the sight glass 29 is arranged on the collecting hopper 20. Accordingly, the staff can also observe whether the filter device 22 is blocked from the sight glass 29, so as to clean the blocked filter device 22 in time.
[0060] The above merely illustrates the specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which shall be covered within the protection scope of the present application.
